In each of This frame I6 is secured by a pair of hinges I! these hinges, there is a plate 3I which carries the window casement and which has a curved member 32 cooperating with the hinge pin 24 and with the curved portion 33 of the hinge plate 34 secured to the window frame. The hinge plate 34 is cut away at a point directly opposite the hinge pin 24 so that in the position of Fig. 6, the hinge plate 35 can be moved without any difiiculty in the direction of the arrow 35 and away from its cooperation with the hinge pin 24. However, as will readily appear, when the window frame 29 has been rotated but a slight amount from its position of Fig. 6, a portion of the curved member 32 of the plate 3| will lie in such relation to the pin 24 as to prevent outward movement of the plate 3| in the direction of arrow 35.

The construction just described regarding the hinge members used with pin 24, is embodied also in the hinge member 30 illustrated in' Fig. 5. The relation of these hinge elements issuch that if it is desired to open the window casement 28 to a position illustrated in Fig. 9,'initial rotation will take place about hinge pins 23 and 24, with the hinge pin 24 so cooperating with the curved member 32, that immediately upon slight rotation, separation of the hinge members will be impossible. This rotation about the vertical axis of hinge pins 23 and 24 will, however, cause separation of the curved member 32 of hinge 38 from its pin 25' as though there were no hinge at that point. I

If, however, it is desired to open the window casement to its position of Fig. 8, rotation then takes place about the upper hinge pin 28 and hinge pin 24 of the auxiliary hinge 30. In this movement, the hinge 25 with its plates 26 and 21 moves as a unit about the pin 28 carrying with it the window frame 21] as though that frame were hinged directly to pin 28. At the same time, the hinge plate 3| with its curved portion 32 will be separated from pin 24'by its movement in the direction of the arrow 35 shown with reference to Fig. 6. At the same time, it will be apparent that the portion 32 of hinge 30 will co-' operate with the pin 24' to prevent any separation of the two immediately upon slightest rotation of the casement 20 in the direction of m-ovemen illustrated in Fig. 8.

Preferably, but not necessarily, a latch member 36 is mounted on the casement frame 20 for securing the same to the window frame 22 when ever it is desired that rotation take place about the pin 24 upon pressure against the frame 20. The latch 36 prevents the separation of the hinge members 32 and 24 so as to supply rotation about pin 2Q rather than about hinge 3!! upon outward pressure. Preferably also, in cooperation with my invention, it is desirable to utilize some spring means for cooperating with the hinge plates 32 and 32' so that separation of the plates from the pins 24 and 24 will be accompanied by spring resistance which will not be any material hindrance, however. Such springs are illustrated. in Fig. 5 and are denoted by reference numeral 31. It is also desirable to secure to the frame 2!} a universal joint casement holder applied relatively to the window frame 22, so as to maintain the frame 20 in its relation to the window frame regardless of its direction of movement. 7

Whereas, I have now fully described this modifioation of my invention, it will be best'to summarize by indicating that the window frame 29' is mounted on the frame 22 in the usual manner for movement about vertical hinges, whenever desired. There are a pair of such hinges so that the casement may be held in a rigid and. usual manner relatively to the frame 22, even though the mounting of casement 2t relatively to the frame 22 is such that movement of the easement to a position illustrated in Fig. 9 and in extreme displacement from the frame structure 22 is possible. Similarly, because of the particular arrangement, movement of the casement 25! to its extreme position of Fig. 8 will also be possible, while extreme rigidity is maintained.

It is my combination of elements operating in a distinctive manner to mount the window casement for movement about two different axes, while extreme rigidity is obtained, which forms the essence of the present invention. Since my in vention might be embodied in numerous modifications, I do not wish to be limited except as indicated in the claims appended hereto.
